I've always struggled with finding marinades for flank steak but when i made this Flank Steak with Chimichurri recipe all bets were off!
Begin by seasoning flank steak with salt, pepper, chili powder and garlic powder. Place in a bowl and coat in oil and a splash of lemon juice. Let sit and come to room temperature for 30 minutes or let marinate in the frisge for up to 24 hours.
Turn the broiler on high. Put steak on a baking sheet, place on the top rack closest to the broiler and cook for about 4 minutes per a side or until desired doneness. Let steak rest while creating sauce.
In a large bowl combine all ingredients. Sauce can be served as is or blended until smoother. Spread over cooked meat and enjoy!
